Gastroesophageal Reflux Disease for Nexium™ for AstraZeneca

Gastroesophageal Reflux Disease is often mistaken for occasional heartburn but is a serious digestive disorder. The lower esophageal sphincter opens more often that it should, and stomach acid travels up into the esophagus where it can erode the esophageal lining. A layer of mucus protects the duodenum from harsh stomach acid, but H. pylori bacteria damage the protective lining, leading to an ulcer. Endoscopy allows a view inside the esophagus, stomach and duodenum to look for acid damage. For Nexium™ AstraZeneca “When It's More Than Just Heartburn” patient educational brochure.
